I just picked up the LCE this morning.
I created a forza4 1 club "1addicts"
the club tag to find it is 1M.
being that member limit seems to be 100 I doubt it will hold
everybody and pretty much makes it first come first served.
to join go to clubs, join club, and type in "1M" for the clan tag.
I dont see a search by club name feature (which sucks).
I will post this as a new thread as well.
